Supported between the frame members I2 in any preferredmanner is the platen Il shown as being of the flat type and arranged forsupporting the record strips S in smooth flat condition for the recep`tion of the impressions of the type of the typewriting machine (notshown) which is mounted upon the rails I2 for movement over the platenin a well known manner. y

Appropriate supporting means is provided for supporting the transfer orcarbon sheets C in interleaved position withthe record strips S over theplaten i4. Any preferred supporting means may be provided for thispurpose, a carbon sheet roll i! being shown as mounted at one side ofone oi' the rails i2, the sheets C being wound thereon whereby they maybe unrolled to extend trans` versely of the platen I4 to the oppositeside of the latter where they may be secured in any appropriate manner.

'Ihe record strips S are of the continuous traveler type and as manystrips as desired may. be arranged in relatively superposed manifoldingrelation and led forwardly together from the supply into writingposition upon the platen. These record strips may be conveniently foldedalong successive transverse lines into a zigzag folded supply pack suchas indicated at S which is supported in any appropriate manner. Each ofthe record strips is provided with strip controlling apertures S2preferably arranged in two longitudinal series along the strips. Alsoeach strip is preferably provided with a longitudinal series of blankforms or spaces for receiving the written data and each strip may alsobe divided into a longitudinal series of record leaves or pad leaves S3conveniently separated from each other by transverse lines S4 whichmayfconveniently be.

weakened severance lines arranged or spaced coincidently with the foldlines of the supply pack S.

The record strips S may be restrained or held at the forward end of themachine beyond the platen Il by means of an appropriate strip securingdevice -indicated generally at Il, an illustrative form of which isshown in Fig. 6. As shown there is a transverse strip guiding plate i1mounted in which are strip engaging pins Il spaced to correspond withthe lateral spacing of thestrip apertures S2 so as to enter the latterwhen the strips are forwardly fed. These pins are preferably stationaryas shown, the forward or strip engaging faces or sides being constructedor provided with an overhanging lip I9 so as to provide retaining lugsadapted to overlie the strips at the forward edges of the apertures thusavoiding accidental disengagement of the strips after the pins have beenplaced in position in the apertures. 'lhe top face or surface of thepins I8 may, as shown, be rearwardly and downwardly inclined in acontinuously inclined surface 20 from the lip Il to the forward terminalof the pins which is preferably at or near the base. of the pin adjacentto the guiding and supporting plate i1. When the strips are fedforwardly, they will be carried upwardly over this inclined surface 20,thus moving them to disengaged position with the pin; but when they aremoved rearwardly, the lip portion will enter the apertures, thus guidingthe pin into aperture engaging position, holding the strips securelyagainst rearward movement and resisting strip disengagement.

A strip restraining bar or clamp 2i cooperates in conjunction with thepins Il to retain or hold the strips against displacement at theirforward endst` This clamping bar may be provided with a recess at itsunder side for the reception of the pins i 8 and it may be controlled oroperated manually byvmeans of the mechanism diagrammatically shown inFig. '1. supporting levers 22 pivoted at 22. to one end each of whichthe bar 2I is attached. The operating link 24 controlled by the pedal 25is connected to the opposite end of the levers 22, while a tensionedspring 2| is connected to the levers to hold the clamping bar 2inormally in strip restraining position. The release of the bar will :busbe eilected by manual operation of the pedal Spaced rearwardly of thebed of the machine from the strip securing device I8 and preferably tothe rearward of the platen il is a second strip restraining andcontrolling mechanism indicated generally at 21. This controllingmechanism may be in the form of an attachment applicable in operativeposition to completed billing or like machines.

'I'his Icontrolling mechanism 21 includes-a suitable supporting frame 22adapted to be attached to the frame of the machine and arranged tosupport the operating parts of the mechanism. Spaced parallel guidingtrack rails or hars 2l are carried by the frame 2l extendinglongitudinally of the machine. A carriage I is supported forlongitudinal reciprocationl upon the rails 29 through g'rooved rollers2|. The carriage 20 is thus' restrained for longitudinal reciprocationadjacent to and substantially parallel to the path of the record strips.An adjustable tensioned spring 32 is connected to the carriage andanchored as at 2l, being normally tensioned to urge the carriage in arearward direction.

Strip engaging pins Il are mounted upon the carriage 20 for longitudinalreciprocation therewith, there preferably being two such pins mountedupon a unitary supporting bar Il and spaced apart laterally the same asthe spacing of the strip apertures S2. 'Ihe supporting bar 25 isprovided with a rearwardly extending arm Il pivotally mounted as at l1upon the carriage lil to the rearward of the pins Il. Thus, the pins maybe swung upwardly and downwardly upon the mounting pivot I1 into andaway from strip engaging position. The carriage plate 30 is preferablyprovided with elongated apertures 2l for the reception of the pins 2l.'I'he path of the record strips lies immediately above the carriage l0as clearly shown in Fig. 4, so that the aligning pins 34, whenprotruding upwardly tnrough the apertures 2l. will lie immediately linthe strip path in position to contact with the strips and to enter theapertures B2 thereof when the latter are brought into alignment withthepins.

Each of the strip aperture engaging pins Il is provided at therearwardly facing aperture engaging side thereof with a lip or extension3l preferably as shown inclining upwardly and rearwardly from the bodyof the pin which is preferably cylindrical presenting a cylindricalaperture engaging surface disposed beneath the protruding lip 29. Thisupwardly rearwardly inclining lip is preferably quite thin orchisel-edged-at its strip engaging edge and is preferably rounded so asto present a convex engaging edge, or is similarly shaped to adapt it toreadily enter strip apertures when the latter are advanced intoengagement with the lip.

The forwardly facing side of each pin Il is Preferably formed to providethe rearwardly and This includes pivotedl upwardly inclined surface4I).0 This surface preferably converges with that at the opposite sideof thepin so as topresent the chisel-edged strip engaging lip 39. 'I'hesurface 4U is preferably sloped off quite considerably toward the baseof the pin as shown so asv to adapt it to swing out of aperture-engagingposition Without injury to the aperture walls. For this purpose surface40may be curved substantially concentric with the pivot mounting 31.rounded transversely of the pin axis so 4as to'present a surface whichis convex transversely of the strip path this formation `also enablingthe pin to engage or disengage smoothly with the strip apertures, andwithout injury to the walls of' the latter. The pins are preferablyprovided with threaded supporting shanks 4I whereby they are firmlyattached `in correctly aligned position to supporting bar 35.

A stressed spring 42 normally urges the pin supporting bar 35 intonormal position shown in Figs. 2 and 4, and the pins may be retracted bya manually operated mechanism. For this purpose, an operating lug 43 ismounted for longitudinal reciprocation in a supporting bracket 44attached to the bar 35, said lug being yieldingly urged into extended oroperative position by means of a compression spring 45. 'Ihe upper sideof the lug 43 is fiat, while its underside has an inclined surface 46adapted to engage with the operating plunger 41 mountedfor verticalmovement in a supporting bracket 4,8 carried by the framework 2li.v Aspring 49 is connected to the operating plunger 41 normally urging thelatter into. its upper operative position as shown in Figs. 2 and 4.This operating plunger is connected-by an adjustable link with theoperating pedal 25. The operating plunger is' thus positioned forengagement with the upper fiat face of the retractable lug 43 when thecarriag'e3 is moved forwardly with the record strips against the tensionof spring 32 tothe position shown in Fig. 4. -Forward movement of thecarriage may be limited by the brackets 51vwhich thus function as stoplugs andl may be providedwith cushion bumpers. When thus positioned,depression of the plunger 41 by operation ofthe pedal 25 will swing thepins 34 downwardly about the pivotal point 31 as an axis.`

Guiding means are preferably provided vto guide-the` record stripsyieldingly into engagement with'the aligning pinsthe strip guidingtensioned spiral springs 53 being very convenient anddesirablefor thispurpose. These guiding springs 53 are preferably mounted in operativeposition Iby suspending them in tensioned condition upon ajmovablesupporting 'frame 54 pivotally mounted for swinging movement at55 near one side of the carriage.

Although the strip guiding and supporting frame 54 does not form a partof the present invention except in combination, it may be noted that theside bars extend transversely of the record lstrip path immediately`above the latter, whereby it may be swung upwardly upon its pivotalsupvpor't 55 away from operative position.. Spring their longitudinaldimensions extending substantially longitudinally of the strippath andthey are positioned adjacent to the strip controlling pins 134 so as toyieldingly position the record strips This` surface `is also preferablyvin their feeding movements in position for proper cooperation with saidpins.

The objectsand nature of the invention having been set forth and anillustrative embodiment described in detail, the operation of theimproved device, embodied in largedegreein the above description, willnow be clear and may be brieiiy summarized as follows:

Any desiredvnumber of record strips may be assembledand fed forwardlyinto writing position upon the platen I4 either by hand,l or if desired,by an appropriate feeding mechanism. Prior to this feeding movement',the record strip controlling device including the pins 34 will'occupythe position shown in Fig. 2, the controlling carriage 30 then being inits rearward retracted position in which it is yieldingly held bythespring 32.

As'the record strips are thus fed forwardly, l

they 'are yieldingly urged by the pliable guide springs 53 intocooperative relation with' the controlling pins 34. Thus, the pinsoccupy an advantageous position for seeking out and'entering thecontrolling apertures S2.

If the strips are slightly out of alignment with each other eithertransversely or longitudinally thereof, the novel pin structuredescribed including the lip portion 39 is especially well adapted to.seek and enter the apertures even though said apertures maybeobstructed by thetransverse or longitudinal disalignment of the strips.Even when the apertures are nearly or fully closed by such disalignment,these pins are very efficient inv finding their way into all of theapertures, thus aiding greatly in bringing the strips into correctlyaligned superposed vrelation with each other.

Continued advancement of the strips after the pins have entered theapertures will cause the controlling carriage 30 to move forwardlyagainst the tension of spring 32 until'the forward strip apertures arebrought a short distance in advance of the forward pins I8 before beingchecked by ,the brackets 51. 'The strips are then allowed toretract'rearwardly slightly by virtue of the tensioned spring 32,causing the hooked ends of the pins to be entered in the strip aperturesand bringing said apertures against the forward lipped side oftheforward pins I8. The record `strips are aligned, tensioned, and smoothedin` correct writing position over the platen I 4, whereupon theinscription may beinade.

When the record strips are fed forwardly as just described,A it will beunderstood that the pedal 25 is depressed, thus raising the front stripretaining bar I6 to release the forward ends of the strips, and at thesame time depressing the operating plunger 41. Therefore, when thecarriage 30 movesl forwardly with the advancing strips, the operatinglug 43 for the pins :I4`

will be positioned to directly overlie the operating plunger 41. Uponrelease of the pedal, the

plunger 41 is moved upwardly by spring 49 engaging the inclinedsurface'46 to cause retrac` tion of the lug 43 until the plunger 41occupies the operative overlying position as shown in Fig.

4. The parts occupy this position during the writing operation. Aftercompletion of the writing, the next operative cycle may be initiated.That is, the inscribed parts of the record strips are fed forwardly asabove described, 'whereupon they may be torn off across the forward edgeof the bar l5, or they may be severed in any other preferred manner. Asthe pedal 25 is depressed preceding this strip feeding action,v descentof the plunger 41 carries the pin supporting bar 35 downwardly about thepivotal support 31 thereof. This pivotal movement causes the controllingpins 34 to descend with a pivotal or rotary motion about the point 3l soas to carry the aperture engaging side of the pins slightly forwardlylongitudinally whereby the pins are caused to disengage the apertureswith an aperture freeing action. By virtue of this action the lippedstrip engaging portions I9 of the pins are carried forwardly to asufficient extent to free the walls of the apertures, thus avoidingobstruction to pin withdrawal, or tearing or otherwise marring theaperture walls. Also, during this aperture disengaging movement of thecontrolling pins, the convexed or curved surfaces 4l of the pins areeffectual in avoiding any obstruction or injurious engagement of thisside of the pins with the opposite or forward walls of the stripapertures. Therefore, by virtue of this arrangement, the pins mayreadilybe withdrawn vfrom aperture engagement without any obstructionwhatsoever and without any tearing or marring of the strips. At the sametime the lipped construction 39 of the controlling pins not only greatlyaids entry of the pins into aligning and controlling position in theapertures, as above described, but it also aids very materially inretaining the strips in controlling engagement with the pins, largelybecause of the strip overlying lips or extensions When the pins arefully withdrawn from the aperture as shown in Fig. 5, the carriage isfreed from the strips S and is returned by the spring nto its initialposition, as shown in Fig. 2.

In order further to facilitate the withdrawal of the controlling pins Ilfrom engagement with the strip apertures, the lugs $2 are placed uponthe plunger 41 in position to engage with the' v bifurcated bracket Ilwhen said plunger is being elevated upon pedal release and thecontrolling carriage 30 is in its forwardly moved position as shown inFig. 4. As the plunger 41 is thus raised by action of the spring 40, thepins or lugs l2, as they engage with the convexly curved surfaces of thebracket il, will impart a slight forward movement to the carriage Il,thus moving the pins Il slightly away from engagement with the adjacentrear walls of the strip apertures S2.

However, lust prior to this forward movement of the controllingcarriage, the strip gripping clamps Il' positioned to the rearward ofthe writing area of the platen I4 will have been set so as to clamp thestrips in smoothed writing position on the platen while said strips arestill under the smoothing and tensioning influence of the controllingcarriage. It will be understood that the strip clamping device Il' maybe similar to those commonly used in machines of this type and thereforeare herein disclosed diagrammatically merely. As shown thusdiagrammatically in Fig. 7, the clamping device Il is released fromstrip clamping position when the pedal is depressed as for example bydepressing the rearward edge or end of the platen I4 slightly by meansof the operating connection 2l between the operating link 2l and theplaten. The

rstrip supporting surfacev of the platen is thus moved slightly awayfrom clamping members I4" l which may be stationary, thus releasing thegrip at theopposite edges of the strips. K

Thus, when the controlling carriage I0 is forwardly moved as justdescribed by actuation of the plunger l1, the strips have already becomeclamped at their forward end by the clamp 2| and at the rear end of theplaten by the clamping devices Il'. The forward movement of the carriagetherefore moves the pins 34 away from the strip aperture walls asdescribed. Being thus freed from engagement with the aperture walls thepins 34 may move freely to disengaging position as the plunger I1descends thus further insuring that no tearing or other damage to thestrip apertures will be caused when the pins are withdrawn. Also, itwill be observed that the rearward movement of the carriage afterwithdrawal of the pins I4 from strip engaging posi tion cannot beinitiated until the lugs l! have passed downwardly beyond the end of thebracket BI. This prevents any premature movement of the carriage whichmight result in damage to the strips or to the walls of the stripapertures.

Since certain changes may be made in the above construction anddifferent embodiments of the invention could be made without departingfrom the scope thereof, it is intended that al1 matter contained in theabove description or shown in the accompanying drawings shall beinterpreted as illustrative and not in a limiting sense.
